Structural And Hardness Of Nonlinear Optical L-alanine Single Crystals

Volume 2, Issue 3, Page 176-182 | DOI: 10.5185/amlett.2011.1219

Abstract: 

Single crystals of pure and Deuterated L-alanine have been grown by both slow cooling and seed rotation techniques. The grown nonlinear optical crystals were subjected to single crystal X-ray diffraction for determining its lattice parameters and morphology. Thermal expansion measurements were carried for the Deuterated crystals of L-alanine using thermomechanical analyzer in order to ascertain the strain tensors along the three mutually perpendicular crystallographic directions. Microhardness study was also undergone on deuterated L-alanine single crystals on a prominent plane for determining the mechanical strength of the grown crystals. The results have been discussed in detail. Copyright © 2011 VBRI press.
